Lecture II
This is the way we take today, because our knowledge is pursuing an inverted path. If we look at the development of our knowledge, we must admit that it starts from the differentiation of the separate senses and then tries to climb up to the conjoint sense. Evolution goes the other way round. During the evolution of the world, Manas first evolved out of Ahamkara and then the primeval substances differentiated themselves, the forces which form the separate senses that we carry within us. (By which we do not mean those material sense-organs which belong to the physical body, but forces which underlie these as formative forces and which are quite super-sensible.) Therefore when we descend the stages of the ladder of the evolution of forms, we come down from Ahamkara to Manas, according to the Sankhya philosophy; then Manas differentiates into separate forms and yields those super-sensible forces which build up our separate senses. We have, therefore, the possibility-because when we consider the separate senses the soul takes a part in them—of bringing what we get out of Sankhya philosophy into line with that which our teaching contains. For Sankhya philosophy tells us the following: In that Manas has differentiated itself into the separate world-forces of the senses, the soul submerges itself—we know that the soul itself is distinct from these forms—the soul immerses itself into these different forms; but inasmuch as it does so, and also submerges itself into Manas, so it works through these sense-forces, is interwoven with and entwined in them. In so doing the soul reaches the point of placing itself as regards its spiritual soul-being in connection with an external world, in order to feel pleasure and sympathy therein. Out of Manas the force-substance has differentiated which constitutes the eye, for instance. At an earlier stage, when the physical body of man did not exist in its present form (thus Sankhya philosophy relates) the soul was immersed in the mere forces that Constitute the eye. We know that the human eye of today was laid down germinally in the old Saturn time, yet only after the withdrawal of the warmth organ, which at the present day is to be found in a stunted form in the pineal gland, did it, develop—that is to say, comparatively late. But the forces out of which it evolved were already there in super-sensible form, and the soul lived within them. Thus Sankhya philosophy relates as follows: in so far as the soul lives in this differentiation principle, it is attached to the existence of the external world and develops a thirst for this existence. Through the forces of the senses the soul is connected with the external world; hence the inclination towards existence, and the longing for it. The soul sends, in a way, feelers out through the sense-organs and through their forces attaches itself to the external world. This combination of forces, a real sum of forces, we unite in the astral body of man. The Sankhya philosopher speaks of the combined working of the separate sense-forces, at this stage differentiated from Manas. Again, out of these sense-forces arise the finer elements, of which we realise that the human etheric body is composed. This is a comparatively late production. We find this etheric body in man.
